It's not a lemon with 98,000 miles on it. Usually a cracked block is the result of a cooling system failure. Such as coolant freezing due to lack of antifreeze or pouring cool/ cold coolant into a hot engine. The rapid temperature change causes the block to crack. When coolant freezes it expands. If the freeze plugs are rusty and don't "pop" as they should the block will crack as well. HTH. -Jim
